Any custom models made for this map can be used for whatever mod you want.
Credits:

Carnivorous- Used his Guard melee action blocks and footsteps patch, assisted me with action blocks and setup creation. Allowed me to use his blocks for the countdown timer and alarms. Fixed a weird issue I was having with plane bounding box.

CrashOveride - Porting PPSH and it's world model, console testing.

Renegadist - supplying sound effects used for the alarms.

Graslu00 - Pinging me on Discord to motivate me to finish the mod.

ZoinKity - used his 7 MB patch

I am glad for my first mod release. Any custom assets in the mod can be used by anyone else with credit.
